TCG: Fix Darwin/ppc calling convention recognition

5da79c86a3744e3a901c7986c109dd06951befd2 broke compilation on Mac OS X v10.5 ppc.
Apple's GCC 4.0.1 does not define _CALL_DARWIN. Recognize APPLE again as well.

tcg: Add TYPE parameter to tcg_out_mov.

Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64
to perform the move at the proper width, which may elide a REX prefix.

Introduce a TCG_TYPE_REG enumerator to represent the "native width"
of the host register, and to distinguish the usage from "pointer data"...

Split TLB addend and target_phys_addr_t

Historically the qemu tlb "addend" field was used for both RAM and IO accesses,
so needed to be able to hold both host addresses (unsigned long) and guest
physical addresses (target_phys_addr_t). However since the introduction of...

tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.

Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands
sign-extended in 64-bit registers (regardless of the "real" sign
of the operand). For that, we need to be able to distinguish
between a 32-bit load with a 32-bit result and a 32-bit load with...

frequent and R3 through R12 are volatile moving this down results in
less spills and tighter generated code....
